Back frame and backlight system

摘要

The present invention provides a back frame of flat panel display device, which includes primary assembling pieces, secondary assembling pieces, and an adjustable bracing piece. The primary assembling pieces have a number of at least two, and the at least two primary assembling pieces are connected through joining to form a main frame structure of the back frame. The secondary assembling pieces are joined to the primary assembling pieces. According to practical needs of the main frame structure, different materials are used for primary assembling pieces at different locations. The back frame further includes the bracing piece that is mounted to the primary assembling pieces or the secondary assembling pieces. The available mounting points between the bracing piece and the primary assembling pieces or the secondary assembling pieces are of a number of at least two so that the bracing piece is selectively mounted to the back frame at different positions. The present invention also provides a backlight system. The back frame and the backlight system of the present invention have a simple back frame structure, reduce the expenditure of the back frame mold, and also save the material used for back frame so as to lower down the cost of flat panel display device and meet different requirements for mounting.
